Creating a key based on a string

Hi all,

I have to create, using the java packages, a secret symmetric key with algorithms such as AES or DESEDE.

I want to create the key based on a random string I create (This is not the string I encode or decode, this is a string which should characterize the key itself!!).

How can I do this using java code? Somebody has an example?

Thanks,

Amr.
